Description

Updating device and method therefor

The present invention relates to an updating device and an updating method.

Most current quartz watches include a date disc. Nevertheless, for certain last days of the month, such as February, April, June, September and November, the user must ensure that the date of the following month is correct, i.e. that the displayed date is "29", "30" or It should verify that it is "1 day" and not "31".

Perpetual calendars exist, but their algorithms and/or clocks are very complex, as this requires considering all possible cases.

If the user changes the time zone, for example from Europe to Asia, it all gets more complicated. In this case, the date change by the perpetual calendar is performed before the date change of the internal clock, which induces an error requiring user intervention.

The present invention proposes to solve all or part of these deficiencies by means of a device for updating the date on a watch, said updating device comprising:

- a memory, said memory configured to transmit a current date according to a programmed perpetual calendar for a time zone;

- at least one date disk, said at least one date disk comprising a first part and a second part;

- a first sensor, said first sensor configured to transmit a first signal when said first sensor detects said second portion;

- a driving member, the driving member being configured to drive the at least one date disk;

- a second sensor, the second sensor being configured to transmit a second signal when the second sensor detects the driving of the at least one date disk by the driving member; and

- a central unit, wherein the central unit compares the first signal with a current date and when the first sensor detects the first part of the at least one date disk if the second part is different from the current date and receive the second signal before controlling driving of the at least one date disk to the driving member.

With this arrangement, regardless of the user's location, the date change is performed precisely and simply in this way.

According to one embodiment, said time zone is a time zone from time zone “+10”, “+11”, “+12”, “+13” or “+14”.

With this arrangement, the date change of the perpetual calendar of the internal clock of the memory is performed first.

According to an embodiment, said at least one date disk comprises a date disk or two date disks; The two date discs are a date unit disc and a date tens disc.

With this arrangement, the updating device operates on a date disk or on a large date.

According to an embodiment, said first part of said date disc represents dates 1-28 and said second part of said date disc represents dates 29-31, or said first part of said two date discs denotes date tens 0 and 1 and date tens digit 2 to 8, and the second part of the two date disks denotes date tens digit 2 and 3 and date tens digit 0, 1 and 9 date quartiles.

By this arrangement, it is possible to distinguish very simply the last days of short months which do not contain 31 days, such as, for example, February, April, June, September, and November.

According to an embodiment, said first part is different from said second part.

According to an embodiment, said first sensor is a first optical sensor, a first resistive sensor, a first capacitive sensor and/or a first inductive sensor.

With one or the other of these aforementioned arrangements, a single first sensor is sufficient to distinguish the first portion from the second portion.

According to an embodiment, said second sensor is a second optical sensor, a second resistive sensor, a second capacitive sensor and/or a second inductive sensor.

With this arrangement, it is possible to detect a date change performed by the at least one date disk.

According to one embodiment, the drive member is a motor.

With this arrangement, it is possible to drive the at least one date disk.

The present invention relates to a method for updating a date for a clock implemented by an updating device according to the present invention, said updating method comprising:

- storing the current date in memory according to the programmed perpetual calendar for the time zone;

- receiving a second signal, the second signal being transmitted by a second sensor configured to detect the driving of the at least one date disk by the driving member;

- verifying a first signal after receiving said second signal, said first signal being transmitted by a first sensor when said first sensor detects a second portion of said at least one date disk , verifying the first signal;

- comparing said second signal with a current date;

- if the second part is different from the current date, controlling the driving of the at least one date disc with a drive member until the first sensor detects the first part of the at least one date disc do.

With this arrangement, regardless of the user's location, the date change is performed precisely and simply in this way.

According to one embodiment, said time zone is a time zone from time zone “+10”, “+11”, “+12”, “+13” or “+14”.

With this arrangement, the date change of the perpetual calendar of the internal clock of the memory is performed first.

The present invention thus makes possible a simple and accurate date change, regardless of the user's location. In practice, quartz watches with calendars are generally calibrated to the time zone in which the battery change occurred or to the time zone of the factory for which the calendar was designed. As soon as the user moves and changes time zones, such adjustments may clearly misadjust the calendar function and cannot make it work during the last days of "short months". The difficulty is real, since, in principle, the watch does not know which area the user has moved to. Complexity arises when traveling, especially in certain cases crossing the date line, such as in the case of travel to Asia, for example.

The present invention allows the user to simply adjust the time and date corresponding to the area in which he is located, ie the area in which he lives, or even just traveled, and with a single adjustment of the perpetual calendar during battery changes, for example , allows the watch to manage the last days of "short months" such as February, April, June, September, and November.

To this end, the invention is in the form of a device 100 for updating a date on a watch which implements an updating method 500 .

The updating device 100 of FIG. 1 comprises only a memory 170 , at least one date disk 120 , a first sensor 130 , typically a first optical sensor 130 , a first resistive sensor 130 . ), a first capacitive sensor 130 and/or a first inductive sensor 130 , a drive member 160 , a second sensor 180 and a central unit 150 .

During factory adjustment and even later, the current date 171 is stored in the memory 170 according to the programmed perpetual calendar for the time zone 175 in the memory (570). In practice, the perpetual calendar of the internal clock of the memory 170 is a time zone 175 from a time zone 175 "+10", "+11", "+12", "+13" or "+14". and transmits the current date 171 according to the time zone 175 , which enables a date change in the perpetual calendar first of all, especially when the time zone 175 is the time zone 175 "+13". Indeed, these time zones 175 are for changing the date first in FIG. 4 , more specifically time zone 175 “+13”.

2a to 3b , the at least one date disk 120 comprising a first part 126 and a second part 127 is shown. More precisely, in Figs. 2a and 2b a date disk 121 is illustrated, and in Figs. 3a and 3b two date disks 122 for a "large date" are the date one's digit disk and date It is displayed as a deciduous disk.

2a and 2b, the first portion 126 of the date disc represents dates 1-28 and the second part 127 of the date disc represents dates 29-31. On the other hand, in the embodiment of FIGS. 3A and 3B , the first part 126 of the two date disks 122 represents the date tens 0 and 1 and the date tens digits 2 to 8, The second part 127 of the two date disks 122 represents the date tens digits 2 and 3 and the date digit 0, 1 and 9 digits.

If the updating device 100 includes only the first sensor 130 , it is sufficient to distinguish a first part from a second part which is different from each other, so that the first sensor 130 makes the second part 127 ), no signal is transmitted unless the first sensor 130 detects the second part 127 of the two date disks 122 to transmit the first signal 131 when detecting does not This makes it very simple to distinguish the last days of the months February, April, June, September and November.

The second portion 127 of the at least one date disk 120 is connected via the drive member 160 , typically a motor 160 , configured to drive the at least one date disk 120 . 1 is opposed to the sensor 130 .

At each date change, ie each time the drive member 160 drives the at least one date disk 120 , the second sensor 180 , typically the second optical sensor 180 , the second The resistive sensor 180 , the second capacitive sensor 180 , and/or the second inductive sensor 180 is configured such that when a date jump is detected, that is, the second sensor 180 activates the driving member 160 . ) transmits the second signal 181 when the driving 585 of the at least one date disk 120 is detected. This detection occurs when a jump of the at least one date disk 120 occurs, ie, during updating of the displayed date, when a date jump of clock movement causes a sudden drop in the torque after the torque increase.

The central unit 150 receives (580) the second signal (181) transmitted by a second sensor (180), and the first sensor (130) controls the second of the at least one date disk (120). When detecting the second portion 127, the first signal 131 transmitted by the first sensor 130 is verified (530). A comparison 510 of the second signal 181 with the current date 171 follows.

If the first sensor 130 detects the first part 126 , the central unit 150 will not respond to this information. On the other hand, if the first sensor 130 detects the second part 127 and detects that the current date 171 does not correspond to the last day of the month, that is, the first sensor 130 detects the Upon detecting the dates from "29", "30", and "31" via the second part 127 and detecting that the current date 171 is "1 day", the central unit 150 is configured to: with the drive member 160 until a first sensor 130 detects the first portion 126 of the at least one date disk 120 which will also correspond to “one day” ( 120) to control the drive.
